I would not recommend going back to get the missed reps. However, I would recommend slowing down the progression, as routinely missing reps/overshooting is a significant issue that should be addressed. Adding weight faster doesn’t make you stronger, especially if you end up doing less volume or making the task more fatiguing than it’s supposed to be. I would aim to be conservative in adding weight, if possible.
I just discovered the article on RPE. I hadn’t seen it before and got the subscription, so didn’t have the supplementary ebook and much to read….
Short version is RPE makes sense now and I’ve started doing the proper warm up and then the 4 ramp up sets before the proscribed sets. I assume this will improve the accuracy.
I do wonder on the 4 ramp up sets, are you still doing low reps line the warm up or do you do the same number of reps in the proscribed sets (4, 7, 10 usually)? This was clear to me on the doc.
I usually recommend beginners do the prescribed number of reps for the work sets during the warm-ups. I think that this helps them pick better weights without overshooting
